Here is what i need done to my profire contact me with your price if you are able to perform this mod.

It cost me about 20$ for ICs and other stuff.
I changed all opamps to ne5532, except rear inputs: rear input is opa2132; biased all opamps' to class A via precision resistors, shunted all electrolite caps with small polypropylenes, increased caps in power rails, and boosted headphones amps changing feedback resistors. That's all.
